‘God’s Truth’: Kant, Mill and moral epistemology in Oliver Twist

This essay aims to demonstrate how Dickens’s search for ‘truth’ (and his understanding of what that abstraction consists of) entered into and emerged from one of the key philosophical discussions of the early nineteenth century: namely whether moral knowledge is the sum of one’s experiences or whether there are such things as a priori or ‘natural’ principles of ethics that transcend human practice.

Comment on “A modified leapfrog scheme for shallow water equations” by Wen-Yih Sun and Oliver M.T. Sun

A recent paper published in this journal considers the numerical integration of the shallow-water equations using the leapfrog time-stepping scheme [Sun Wen-Yih, Sun Oliver MT. A modified leapfrog scheme for shallow water equations. Comput Fluids 2011;52:69–72]. The authors of that paper propose using the time-averaged height in the numerical calculation of the pressure-gradient force, instead of the instantaneous height at the middle time step. The authors show that this modification doubles the maximum Courant number (and hence the maximum time step) at which the integrations are stable, doubling the computational efficiency. Unfortunately, the pressure-averaging technique proposed by the authors is not original. It was devised and published by Shuman [5] and has been widely used in the atmosphere and ocean modelling community for over 40 years.

"The Poet of Science": how scientists read their Tennyson

Tennyson’s responses to science have been thoroughly documented and discussed, but how did scientists respond to his poetry? Through examining in detail the work of three scientists who wrote at length about Tennyson--the astronomer Norman Lockyer, the physicist Oliver Lodge, and the American geologist William North Rice--it is possible to see how Tennyson went from being respected by contemporary scientists to being feted as the Poet of Science itself after his death. As a materialist, a Spiritualist, and a Darwinian Methodist respectively, Lockyer, Lodge, and Rice had very different conceptions of how science worked and what it implied about the universe, yet each looked to Tennyson and his poetry to confirm and extend his own judgements and values.

Poetry on Pre-Raphaelite principles: science, nature and knowledge in William Michael Rossetti’s 'Fancies at Leisure' and 'Mrs. Holmes Grey'

This article demonstrates how early Pre-Raphaelite poetry worked according to the principle that art should be modelled on science theorised by the Pre-Raphaelites in their early essays. As the main theorists (rather than practitioners) of Pre-Raphaelite art, F. G. Stephens and William Michael Rossetti defined the Pre-Raphaelite project in terms of observation, investigation, experiment, the “adherence to fact” and the “search after truth”. In the hands of the early Pre-Raphaelite poets, and particularly Rossetti himself, poetry too becomes a mode of scientific enquiry into the natural world, the nature of observation, human psychology and medical practice.
